What is Bandwidth of Communication channel?

The bandwidth of a communication channel refers to the range of frequencies that can be transmitted over that channel, typically measured in hertz (Hz). It determines the data transfer rate or capacity, indicating how much information can be sent in a given time period. A higher bandwidth allows for more data to be transmitted simultaneously, improving the speed and performance of the communication. Essentially, bandwidth is crucial for determining the efficiency and quality of data transfer in various communication systems.
